DETAILED DESCRIPTION

Referring initially to FIG. IA, illustrated is an isometric view of one embodiment of a sub-rack module 100 constructed according to the principles of the present invention. The sub-rack module 100 comprises an open-ended support module 100 having a top 101, a bottom 102, first and second sides 103, 104, respectively, an optional central divider or partition 107, first and second mounting flanges 108, 109, respectively, and a through aperture 114. The through aperture 114 extends from a front 111 of the open-ended support module 100 to a rear 112 of the open-ended support module 100. In one embodiment, the through aperture 114 has a side-to-side width sufficient to receive at least one computer chassis therein. However, in other embodiments, the through aperture's 114 width is sufficient to provide for two or more computer chassis 120. In one aspect, the through aperture 114 is partitioned into first and second computer chassis sub-bays 105, 106, respectively. The partition 107 may be a panel or a bracket, as shown, and may serve as additional support structure for the open-ended support module 100. The mounting flanges 108, 109 may be configured as shown with which bolts and nuts can be used to removably secure the open-ended support module 100 to a support frame. However, in other embodiments, the mounting flanges 108, 109 may include other means such as friction clamps that can be used to removably secure the open-ended support module 100 to a support frame.

In an alternative embodiment, the open-ended support module 100 may further include notches 113 in the first and second sides 103, 104, respectively, adjacent the rear of the open-end support module 100. As mentioned below, the notches 113 can serve as an opening to facilitate air flow into the back end of the computer chassis 120. When present in certain embodiments, the first and second mounting flanges 108, 109, respectively, extend laterally from the front end 111 on opposing sides of the open-ended support module 100. The open-ended support module 100 may be constructed of any suitable rigid sheet-like material such as sheet metal or hard plastic that is sufficiently strong to support the weight of the open-ended support module 100 or modules.

Referring now to FIG. 1B, illustrated is an isometric view of one embodiment of a computer chassis 120 constructed according to the principles of the present invention. Though the computer chassis 120 is not limited to any particular size, it is particularly advantageous that the computer chassis 120 is compact in size and significantly smaller that typical desk top models; that is the length may typically vary between about 12, 16, and 18 inches, while the overall width may vary between about 6 to 8 inches, and the thickness may be about 3 to 4 inches. The compact size of the computer chassis 120 is particularly advantageous in that the units can be centralized in one location, as opposed to computer chassis being located at multiple stations. The centralization provides greater control over the individual computer chassis, and given that they can be centralized in one location, security can be much improved. However, such centralization and the racking of multiple heat generating computer chassis gives rise to serious cooling considerations, which is what the present disclosure addresses.

In one embodiment, the computer chassis 120 comprises main and secondary cooling fans 121, 122, respectively; and top, side and front ventilation apertures, 123, 124, 125, respectively, and an optional swingable handle 126. The cooling fans 121, 122 and the ventilation apertures 123, 124, and 125 allow for an air flow in a direction that is from the back to the front of the computer chassis 120, and indicated by the large arrows shown in FIG. IB. In this particular embodiment and when used in conjunction with the open-ended support module 100, this air flow allows for efficient cooling when multiple computer chassis 100 are racked together in one central location.

The main and secondary cooling fans 121, 122, respectively, are internal to the computer chassis 120. For clarity, the other components of the personal computer within the computer chassis 120, e.g., hard drive, motherboard, microprocessor, etc., are not shown and may be of conventional design. Ambient cooling air is drawn in through the top and side ventilation apertures 123, 124 by the main cooling fan 121. The air, having been heated by the electronics of the personal computer, is expelled through the front ventilation apertures 125 with the assistance of the secondary cooling fan 122. The optional swingable handle 126 is rotatably coupled to the upper front corners of the computer chassis 120 and may be used to carry, remove, and insert the computer chassis 120 into the first or second through apertures 105, 106, respectively. The mouse and keyboard connect to the computer chassis 120 over Ethernet. The end user can plug in any USB device at the client side and the signal is carried to the computer chassis 120 over Ethernet. The computer within the computer chassis 120 decodes the signal from Ethernet to USB and sees the mouse and keyboard. Power, Ethernet and PCoIP signal as made through the front panel of the computer chassis 120.

Referring now to FIG. 2, illustrated is an isometric view of the open-ended support module 100 with two personal computer chassis 120 inserted therein. In this illustrated embodiment, the first and second computer chassis sub-bays 105, 106 are configured to each receive the personal computer chassis 120 therein, and the open-ended support module 100 has a front 111 to rear 112 length 127 such that the top ventilation apertures 123 adjacent the back end of the computer chassis 120 extend beyond the rear 112 of the open-ended support module 100. This cooperative configuration is particularly advantageous in that the air flow from the back to the front of the computer chassis 120 is not blocked or inhibited by any portion of the open-ended support module 100. Optional notches 113 in the first and second sides 102, 103, respectively, permit additional cooling air to enter through the side ventilation apertures 124 when the personal computer chassis 120 is fully inserted into the first and second computer chassis sub-bays 105, 106.

Referring now to FIG. 3, illustrated is one embodiment of an isometric view of 12 open-ended support modules 100 with two personal computer chassis 120 inserted in each open-ended support module 100 of a multi-position support rack 300. The multi-position support rack 300 comprises a plurality of frame support members 305 coupled together to form a plurality of support locations for the open-ended support modules 100. The mounting flanges 108, 109 are configured to cooperate with the frame support members 305 to removably fasten the open-ended support modules 100 at the desired support locations. The top and sides have been removed from the multi-position support rack 300 for better viewing of the contents.

The two stacks of six open-ended support modules 100 with 12 personal computer chassis 120 each are located on opposing sides of the multi-position support rack 300 and are advantageously arranged such that the back ends of the computer chassis 120 oppose each other. This unique configuration forms an air passageway 310 between the rears of the two stacks of personal computer chassis 120 and forms an open air conduit for air to flow from the air passageway 310, through the computer chassis 120 and out the opposing sides of the multi-position support rack 300. More specifically, air flows into the top and optional side ventilation apertures 123, 124, respectively, of each of the personal computer chassis 120 and out the front ventilation apertures 125. This unique configuration allows for efficient cooling of multi-heat generating personal computers, while allowing them to be racked in a single centralized location.

While a multi-position support rack 300 with 24 personal computers is illustrated, one who is of skill in the art will recognize that the multi-position support rack 300 may comprise any number of open-ended support modules 100 arranged so as to position the computer chassis 120 mounted therein with the rear ends of the chassis opposing.

Thus, a stackable modular personal computer array has been described that concentrates the computer hardware in one large, multi-position support rack. Therefore, air conditioning can be provided to accommodate the heat output of the stackable modular personal computer array. With all of the computers commonly located, information can be accessed by any authorized used remotely from the computer array anywhere in the company as well as the information technology technician does not need to walk back and forth from the server room to the office with a computer problem. Furthermore, connecting a keyboard, mouse, etc., can be readily accomplished to a problem computer and diagnosis made. If necessary, the problem computer can be removed from the open-ended support module and replaced with a known good computer.
